2011 Chevolet Volt: Keeps the Pressure On
February 21, 2011
I checked our long term 2011 Chevrolet Volt's tire pressure recently and found both front tires at 32.5 psi, while the rear tires were at 34 and 34.5 psi. The little sticker in the driver's door frame says all four tires should be at 35 psi.
Now although proper tire pressure is important in any vehicle, it's doubly so when you're driving a car with a primary purpose of conserving transportation energy.
I was actually pretty sure the tire pressure was low before I checked it, as steering response and bump reaction in the front felt a bit wallowy compared to the Volt I drove at the press conference in Detroit last October (note: the closest I come to having a Jedi force power is being able to detect low or unever tire pressure).
My portable air compressor had all four tires back up to 35 psi in about 5 minutes, and the Volt did feel a tad sharper afterwards, though we're talking very subtle shades of gray with these kinds of pressure changes.
As with our past Prius long-term car, or any future alternative energy vehicles we pick up (yup, another one is about to arrive in the fleet), we'll work hard to keep the tire pressures at factory spec. When you're talking maximum energy efficiency, this is critical.
